2. OPERATING INSTRUCTIONS
2.1 Introduction
DIVAtech F37 D

 is a high-efficiency heat generator for heating and domestic hot water

production, running on natural gas, equipped with an open-flue burner with electronic ig-
nition, sealed chamber with forced ventilation, and microprocessor control system, de-
signed for installation indoors or outdoors in a partially protected place (in compliance
with EN 297/A6) for temperatures to -5°C.

Indication during operation
Heating

A heating demand (generated by the Room Thermostat or Remote Timer Control) is in-
dicated by flashing of the hot air above the radiator on the display.
The display (detail 11 - fig. 1) shows the actual heating delivery temperature and, during
heating standby time, the message 

“d2”

.

Domestic hot water (DHW)

A DHW demand (generated by drawing domestic hot water) is indicated by flashing of
the hot water under the tap on the display.
The display (detail 11 - fig. 1) shows the actual DHW outlet temperature and, during
DHW standby time, the message 

“d1“

.

Comfort

A Comfort demand (reinstatement of temperature inside the boiler) is indicated by flash-
ing of the water under the tap on the display. The display (detail 11 - fig. 1) shows the
actual temperature of the water in the boiler.

Fault

In case of a fault (see cap. 4.4) the display shows the fault code (detail 11 - fig. 1) and,
during safety standby times, the messages 

"d3"

 and 

"d4"

.

2.3 Lighting and turning off
Connection to the power supply

During the first 5 seconds the display will also show the card software release.

Open the gas cock ahead of the boiler.

The boiler is now ready to function automatically whenever domestic hot water is
drawn or in case of a heating demand (generated by Room Thermostat or Remote
Temperature Control).

Turning the boiler off and on

Press the 

on/off

 button (detail 7 - fig. 1) for 5 seconds.

fig. 2 - Turning the boiler off

When the boiler is turned off, the PCB is still powered. Domestic hot water and heating
are disabled. The antifreeze system remains activated. To relight the boiler, press the

on/off

 button (detail 7 - fig. 1) again for 5 seconds.

fig. 3

The boiler will be immediately ready to work whenever domestic hot water is drawn or in
case of a heating demand (generated by the Room Thermostat or the Remote Timer
control).

B

The antifreeze system does not work when the power and/or gas to the unit are
turned off. To avoid damage caused by freezing during long idle periods in win-
ter, it is advisable to drain all water from the boiler, DHW circuit and system; or
drain just the DHW circuit and add a suitable antifreeze to the heating system,
complying with that prescribed in sec. 3.3.

2.4 Adjustments
Summer/Winter Switchover

Press the 

summer/winter

 button (detail 6 - fig. 1) for 2 seconds.

The display activates the Summer symbol (detail 10 - fig. 1): the boiler will only deliver
domestic hot water. The antifreeze system remains activated.
To deactivate the Summer mode, press the 

summer/winter

 button (detail 6 - fig. 1)

again for 2 seconds.

Heating temperature adjustment

Use the heating buttons (details 3 and 4 - fig. 1) to vary the temperature from a min. of
30°C to a max. of 80°C; in any case, it is advisable not to operate the boiler below 45°C.
